Radio Sending and Receiving
Driving home: However, and here is the flip side of the issue, the most earnest, lively, vivid, passionate, Spirit-anointed preaching will do little or no good if it is delivered to an assembly of dull hearers.
The analogy of a radio sending station and a receiving set is used to illustrate that even powerful preaching (sending station) is useless if the hearer's spiritual 'receiver' (ears/heart) is out of order.
One commentator has stated the case most accurately when he said, the difficulty lies not with what the Old Testament says about Melchizedek, not with the writer who knows what is said, but with the hearers and their sluggish ears. The sending station was in order, but the receiving radio set was out of order. You see the imagery. No matter how powerful it is.
